Answer 1

Amphibian means two-lives. They spend their lives in water and on land.

Amphibians are cold-blooded, ectothermic animals. They also come under the class vertebrates (meaning they have backbone or spine).

Amphibians breathe through skin and they go through metamorphosis.

Amphibians begin their life in water with gills and tails. They develop lungs and legs as they grow for their land life.

60 million years ago amphibians were the dominant terrestrial animals on earth.
